To all whom it may concern:

Be it known that I, HARRY E. Roan, a citizen of the United States, and a resident of the city of New York, College Point,borough of Queens, in the county of Queens and State of New York, have invented a new and improved Aeroplane, of which the following is a full, clear, and exact description.

An object of my invention is to provide ,mechanism, certain features being omitted.

for the foot control of the steering rudder, lift rudder and ailerons of an aeroplane, thereby enabling the pilot of the machine to ,have his hands free for any emergency, or auxiliary duties he may undertake; a more specific object being to cooperate in footcontrolled mechanisms with the usual hand lever, thereby permitting of certain of the operations being carried out e medium of the hand lever if through t The dual foot and desired by the pilot.

, stick control thus give an increased mar-- gin of safety, having in view the possibility of injury to the pilots arms and legs or injury to either the foot-control or hand-control elements. v

A further important object of the invention is to utilize the bodily movement of a foot bar for efiecting the movements of two of the three controlling mechanisms pertaining respectivelyto the steering rudder, lift.

rudder, and ailerons, and to provide a pedal mechanism controlling. the third of said movements and operative independently of the other two mechanisms while coordinated with the latter. 4

An object of the invention, also, is to provide means for maintaining the pedals disposed at opposite sides of the foot board, in

parallel relation and in lines running substantially fore and aft, notwithstanding the turning movement of the foot board in its own plane or the verticalrocking thereof to effect two of the three controlling actions.

The said objects, and others as will appear, are attained in the manner hereinafter explained. Reference is to be had to the accompanying drawings forming part of this specification, it being understood that the drawings are merely illustrative of one example of the invention.

Figure 1 is a diagrammatic perspective view given to show the connections between my controlling mechanisms and the steering rudder, lift rudder and ailerons.

Fig. 2 is a plan view of my improved mechanism. V 1

Fig. 7 is a diagrammatic perspective view omitting certain features shown in Fig. 6

and including certain elements omitted from it will be .understood that the movements of the three controlling mechanisms constituting my foot control may connect respectively with either of the elements to be controlled, that is to say, with the steering.

rudder, with the lift rudder, or with the ailerons. For the purpose of illustration I have shown the ailerons controlled by a vertical rocking or sidewise tilting of the footboard and have shown the pivotal movement of the footboard in its own plane controlling the lift rudder, while the steering rudder is controlled by the vertical rocking of pedals forming part of my improved foot control.

In carrying out my invention in accord-' ance with the illustrated example, a footboard 10 is provided and pivoted centrally by an approximately vertical bolt 11, or the like, in the forked end 12 of a rock shaft. 13

extending longitudinally of the machine, said shaft turning in suitable bearings 14 and 15 on standards 16 and 17 rising from a base 18 secured to the body A of the machine. The turning of the shaft 13 throu h an angle effects control ofthe ailerons here shown associated with the planes B of a biplane. In the illustrated form said'shaft 13 has a grooved wheel 19 thereon at the rear end on which cables 20 wind and extend laterally in opposite directions-to a suitable connectionwith the respective lowerailerons B of the plane shown, the upper and lower ailerons having any approved interconnections E and as conventionally shown. With the described arrangement, either end of the footboard 10 may be depressed to turn the shaft 13 through an angle for actuating bolt 11 as a center, and in the illustrated,

form connections are made between said footboard at opposite sides of its pivotal center 11 and with the lift rudder D by cables 21, said cables being connected with eyes 22, or the like, on the rear edge ofthe footboard and extending from sa1d eyes 1n pairs to the respective upper and lower arms F on the shaft G of said lift rudder. Thus, a turning of the footboard about the pivot 11 in one direction will throw the lift rudder B upwardly, while a reverse turn ng movement of the footboard in its plane about the pivot 11 will impart reverse move ment to the lift rudder. It will thus be seen that the two different movements of the footboard 10, the one a vertical rocking movement and the other a horizontal move ment, effects respectively the control of the ailerons and the lift rudder.

In order to cooperate my foot-control mechanism with the ordinary stick control, as it is termed, I provide a vertical hand lever 23 which is made rigid with a horizontal shaft 24 turning in a transverse bearing 25 in the shaft 13 or otherwise arranged so that the lever 23 and the transverse shaft 24' may have a forward and back rocking movement relative to the shaft 13, While at the same time a lateral vibration of the lever 23 will rock the shaft 13 either to the right or to the left, as desired. Vibration of the lever 23 forward and back pivotal center 11 the footboard 10 is caused to give a turning movement to the footboard 10 in its own plane about the pivot 11, for which purpose oppositely-directed crank arms 26 are provided on the ends of the shaft 24, the arm at one end extending upwardly from said shaft 24 and the crank arm at the opposite end extending downwardly, said crank arms being connected by links or connecting rods 27 with hooks 28, or the like, on the rear edge of the footboard 10 at opposite sides of its thus, the hand lever may be employed to impart the vertical rocking movement to the footbo'ard for controlling. in the illustrated arrangement, the ailerons B, while the forward and back vibration of the lever through connecting rods 27 and control the lift rudder D. Thus, the pilot, trol for the ailerons and lift rudder, will have his hands free for any other duties he may wish to perform; and in the event of injury to the pilots legs, for example, the hand lever may be utilized, or vice versa.

The third element to be controlled, to wit, the steering rudder is in the present example of my invention controlled through the medium of pedals, designated by the numeral 29, disposed respectively adjacent to the opposite ends of the footboard 10, each pedal having a suitable toe strap at the fiont end, as at 30. The rear ends of the the respective lever arms if he utilizes the foot connarratenection of cables 35, which are connected at one end with the respective arms 33 and extend therefrom to'a connection withvthe lever arms H on the shaft I of the steering rudder J. The shaft sections 31 and their arms move oppositely, so that as one arm 33 swings upwardly, the other arm 33 will swing downwardly to give corresponding movements to the cables 35 connecting with H, for which purpose the shaft sections 31 have bevel pinions 36 thereon meshing with'sectors 37 on a gear element or disk 38 loose on the vertical pivot 11, the arrangement being such that a rocking movement imparted to one shaft section 31 will give a reverse rocking movement to the opposite shaft section 31 and its pedal 29'. In order to maintain the pedals 29 parallel, or substantially so, with the longitudinal axis of the machine, the two lever arms 33 are constrained to move vertically in a definite path in rocking, for which purpose the said lever arms-33 extend through slots 39 in an arcuate guide 40 formed on a .base plate 41, secured in the present example by the pivot bolt 11. Also, the lever arms 33 are connected with the pedals 29 by rods 42 parallel with the shafts 31, said rods 42 being'each pivoted at one end, as at 43, to a lever arm 33 and pivoted at its opposite end, as at'44, to a pedal 29. Thus, the pedals are maintained in parallelism with the lever arms 33 and with the definite vertical path of the move-- ment of the latter. The described arrangement is provided to maintain the effective positions of the pedals for direct up and down movement-for rocking the shaft sections 33, the fore and aft positions being maintained notwithstanding the movement of the footboard' 10 about its pivot 11. It will be observed that the connection between the pedals 29 and the shaft sections 31 is by pivots 45.

Heel plates 46 are associated with the pedals but are independent of the latter. I provide for maintaining the relative positions of the heel plates and pedals regardless of movements of the footboard 10, for which purpose said heel plates are arranged to rock vertically, the hinge straps 47 thereon 1n the present example loosely embracing T heads 48, the shanks 48 of which are secured in standards 49 on the ends of a crossbar 51, said standards being pivoted as at 50 to said crossbar and the latter being mounted centrally for vertical pivotal movement by reason of a transverse pivot 52 connecting said crossbar to a short'standard 53 adapted to turn in a step bearin 54 on the base 18 or on the fixed support. The standards 49 have connection with the ends of the'footboard 10 to permit the standards. to rock laterally. The connection may be produced as shown by lateral studs 4:9 on

' the standards 49 enga ed by hinge straps 49 embracing said stu s and secured to the footboard. With the described detail arrangement it will be readily understood that the pedals may be operated to control the steering rudder J through the cables 35 irrespective of the position or movements of the footboard 10 in the control by the latter of the other two controlling elements that is to say, the ailerons B and lift rudder D.

I would here mention that I have referred in the foregoing to the ailerons as such merely as an example of usual stabilizing means, and have referred to the lift rudder. as such merely as an example of elevating means.

In conclusion, I would state that while the illustrated example constitutes a ractical embodiment of my invention, I 0 not limit myself strictly to the mechanical details herein illustrated, since, manifestly, the same can be considerably varied with-, out departure from the spirit of the invention as defined in the appended claims.
